Treatment of Penile Cuts with Mupirocin
For a simple cut on the penis, apply mupirocin 2% ointment three times daily directly to the wound for 5-10 days, which is safe and effective for treating minor skin wounds and preventing bacterial infection. 1, 2, 3
Application Protocol
- Apply a small amount of mupirocin 2% ointment directly to the cut three times daily 3
- The treated area may be covered with gauze dressing if desired 3
- Typical treatment duration is 5-10 days 2
- If no clinical response is seen within 3-5 days, the patient should be re-evaluated 3
Why Mupirocin Works for This Indication
- Mupirocin demonstrates excellent activity against Staphylococcus aureus (including MRSA) and Streptococcus species, which are the most common bacteria that colonize and infect skin wounds 1, 2
- For minor skin infections and secondarily infected skin lesions (such as lacerations), mupirocin 2% topical ointment is specifically recommended by the Infectious Diseases Society of America 1
- The medication is safe for use on genital skin, though it is primarily formulated for intact skin rather than mucosal surfaces 4
When to Escalate Treatment
Consider systemic antibiotics instead of topical therapy if any of the following are present:
- Fever or systemic signs of infection 2
- Extensive surrounding cellulitis 2
- Deep tissue involvement 2
- No improvement after 5 days of topical treatment 2
- Immunocompromised patient with significant infection 2
Important Caveats
- If the cut involves mucosal surfaces (urethral opening, inner foreskin), alternative antimicrobial agents formulated for mucosal use may be more appropriate 4
- For deeper wounds or abscesses, incision and drainage is the primary treatment, with mupirocin as adjunctive therapy only 2, 5
- Avoid prolonged or indiscriminate use to prevent development of bacterial resistance 2
- Local side effects (burning, itching, redness) occur in less than 3% of patients 6
